I flies bell412sp for offshore.
My choppertransmission torque indicates over 100%(about 103%) for 1~1.5 seconds when takeoff at oil rig after 15feet hovering at torque stabilizing 95~98% without collective input.
N1 is 1% differance, ITT is normal. But engine torque spilt about 6% stabilizing at that time.
Only transmission torque moves up.
Then XMSN TQ decrease to 85% until Vtoss also without collective input.
I don't know the reason.
Please let me know if you have this experience, or the reason why?
Thank you
